JOHN WV. MARK, OF NEW YORK, N. Y.

ILLUMINATING-TILE.

SPECIFICATION forming part of Letters Patent No. 416,478, dated December 3, 1889.

Application filed May 2, 1839- Serial No. 309,846. (No model.)

To aZZ whom it may concern:

Be it known that I, J OHN WV. MARK, of New York, in the county of New York, and in the State of New York, have invented certain new and useful Improvements in Illuminating-Tiles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view, from the upper side, of the metal portion of my tile before the light-openings are filled. Fig. 2 is a like view of the same from the lower side. Fig. 3 is a perspective View of the completed tile, and Figs. 4 and 5 are sections upon lines x as and .e 2, respectively, of Fig. 3.

Letters of like name and kind refer to like parts in each of the figures. The design of my invention is to improve the appearance and increase the strength and capacity of illuminating-tiles; and to this end said invention consists in the construction of the body of the tile, and in the combination of the same with the lenses, substantially as and for the purpose hereinafter specified.

In the carrying of my invention into practice 1 construct the metal portion or body of my tile A with a series of six-sided lightopenings a and a, which are arranged in rows, and those of one row have such arrangement with relation to the openings of the adjacent rows as to cause them to present a zigzag or staggered appearance, each of said openings being located opposite to the space between two similar openings of each adjacent row. The openings a and a are formed by three series of bars, thosev of each series being parallel with each other and having relative angles of sixty degrees with the bars of the other series at their points of intersection therewith. This arrangement leaves other and smaller triangular openings or and at, opposite to each side of each of said openings a and a, the contiguous sides of which openings a and a are parallel, as shown. This construction presents an attractive appearance, as each of the larger openings to forms the center of a six-pointed star, of which the surrounding triangular openings at and a constitute the points. The light-openings are each provided at its lower. end with a shoulder a and contain correspondingly-shaped lenses B or B, which are cemented in place tiling may be inserted within the smaller light-openings in place of lenses. It will be seen that the body of the tile, being composed of straight intersecting bars, possesses great strength, and that the construction aifords a maximum of light-opening for a given area of tiling.

Having thus described my invention, whatl claim is 1.v A tile-body composed of a series of parallel bars that are combined with two other series of parallel bars intersecting them, the bars of each of the latter series being continuous and extending in lines inclined to the bars of the former series and to each other, substantially as and for the purpose specified.

2. As an improvement in illuminating-tiles, a body which is provided with six-sided lightopenings and intermediate triangular lightopenings, substantially as and for the purpose shown.

r 3. As an improvementinilluminating-tiles, a tile which is provided with six-sided and triangular light-openings that are arranged with their contiguous sides parallel, substantiallyas and for the purpose set forth.

4. As an improvement in illuminating-tiles, a tile-body which is provided with six-sided and triangular light-openings, in combination with lenses that are fitted to and secured within the same, substantially as and for the purpose shown and described.

5. As an improvement in illuminating-tiles, a tile-body which is provided with six-sided and triangular light-openings, in combination with lenses having different colors, that are fitted to and secured within the same, substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 25th day of April, 1889.
